玻璃鋼(gang)冷卻塔(ta)(ta)風(feng)(feng)(feng)筒(tong)(tong)(tong)設計(ji)(ji)理(li)念：該塔(ta)(ta)風(feng)(feng)(feng)筒(tong)(tong)(tong)為迥轉及“優角(jiao)”動能回(hui)收型(xing)，玻璃鋼(gang)材質，它充分利(li)用了氣體流(liu)暢均化理(li)論，結合工程實(shi)踐經驗和實(shi)測(ce)數據而設計(ji)(ji)，內壁(bi)曲線(xian)(xian)采(cai)用橢(tuo)圓曲線(xian)(xian)，與采(cai)用直線(xian)(xian)的(de)自然擴散(san)型(xing)風(feng)(feng)(feng)筒(tong)(tong)(tong)相比較，該風(feng)(feng)(feng)筒(tong)(tong)(tong)消除了氣流(liu)脫壁(bi)現象，縮(suo)小了渦流(liu)區(qu)，使風(feng)(feng)(feng)筒(tong)(tong)(tong)中心(xin)負壓區(qu)面積大幅(fu)縮(suo)小，出(chu)風(feng)(feng)(feng)口斷面風(feng)(feng)(feng)速(su)分布(bu)趨于(yu)均化。風(feng)(feng)(feng)筒(tong)(tong)(tong)線(xian)(xian)型(xing)設計(ji)(ji)合理(li)，下(xia)部(bu)按《維道辛期基》曲線(xian)(xian)的(de)上半段求出(chu)的(de)公式（化工部(bu)通風(feng)(feng)(feng)圖(tu)設給出(chu)風(feng)(feng)(feng)筒(tong)(tong)(tong)型(xing)設計(ji)(ji)）
